Remote comprehensive eye examination system

ABSTRACT

An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.

FIELD OF THE DISCLOSURE

The present disclosure relates generally to an apparatus, method, andsystem for remote comprehensive eye examinations. This apparatus,method, and system may also be usefully configured to work in variousother arts beyond remote comprehensive eye examinations.

BACKGROUND

Comprehensive eye examinations need to become more accessible in theU.S., since over 75% of adults use some form of vision correction. Butmany areas have a limited supply of optometrists andophthalmologists—the gatekeepers for eye examinations—or such supply maybe reduced during certain days and hours of the week. Access tocomprehensive eye examinations is critical in determining not onlycorrective prescriptions for eyeglasses and contact lenses, but also inidentifying potential diseases of the eye and body, such glaucoma,macular degenerations, and hypertension.

The internet is being increasingly utilized for optical products such aseyeglasses and contact lenses. Further, there are new technologies thatoffer the consumer refractions via smartphones, portable devices, aswell as through the internet on a computer in order to determine thepatient's prescription. Companies and devices that currently offer thistechnology via refraction devices include: Opternative, Smart VisionLabs, Eyenetra, Peek, Pediavision, and 2 win.

But these refraction-based systems do no provide the patient/consumerwith a comprehensive eye examination. While these systems update theirprescription for eyeglasses and/or contact lenses with a device, theyare not able to discover other potential ocular health issues. Indeed,the reduction of vision in the eye and therefore the necessity foreyeglasses and/or contact lenses is the stimulus that motivates apatient/consumer to see an eyecare professional. Thus, patients that usepresent-day internet-based tools for glasses or contacts will not beevaluated for other ocular-related medical issues and will not normallyschedule such visits with an optometrist or ophthalmologist. Withoutsuch visits, important ocular issues could be missed and go undiagnosed.Although extremely convenient, the use of these new technologies withoutproper medical guidance may results in adverse effects for patients, andultimately cause more harm than good.

Accordingly, it is therefore desirable to combine the convenience ofinternet or remote based eye testing with the availability of skilledoptometrists or ophthalmologists into an apparatus, method, and systemfor remote comprehensive eye examinations.

SUMMARY OF THE INVENTION

Embodiments of the present disclosure call for a remote station where anoptometrist or ophthalmologist need not be required to be on-site toperform a comprehensive eye examination. Instead, an ophthalmictechnician is present with the patient in the exam room to operate eyeexamination equipment and transmit patient information to remotelocation. At that remote location, a skilled technician is present toprovide the necessary optical and/or medical care, and may operate thephoropter from the remote location if he/she desires. Using video and/orteleconferencing equipment and a phoropter located in the patientexamination room along with management software, the system works todetermine the final optical prescription for the patient. Thatinformation, coupled with findings from other devices which areintegrated with the management software, and that the patient useslocally, are reviewed by a remote based optometrist or ophthalmologist.

While the patient is being evaluated for eyeglasses or contacts, theoptometrist or ophthalmologist may also operate the phoropter located inthe patient examination room from the remote location if he/she desiresand evaluate the patient for other ocular-related medical issues. Oncethe findings are finalized by the optometrist or ophthalmologistremotely, the final prescription for eyeglasses and/or contact lenses,along with any additional comments or findings, will print locally atthe examination location and be delivered to the patient.

The advantages of this remote station-based approach are widespread.

Patients benefit from the remote station because it provides them with amethod to obtain needed eye care at a time and location that isconvenient to them. Patients also benefit from the peace of mind that askilled optometrist or ophthalmologist will be evaluating them andchecking for ocular issues beyond the need for eyeglasses or contacts.

The optometrist or ophthalmologist benefits by being able to provide hisor her services at times and places of his or her choosing (not unlikethe way a driver works for ride-sharing services, such as Uber, at timesconvenient to him or her). Further, the potential pool of patients forthe optometrist or ophthalmologist is much larger since he or she is notlimited to the market of patients within driving distance of his or heroffice.

The host at the local side of the remote station, where patients arepresent, benefit because the services offered by the system allow forbetter utilization and synthesis of other parts of the host's business.For example, a retail optical store will often lose sales if a customerrequires a prescription to purchase eyeglasses and there is nooptometrist or ophthalmologist in the store to write the prescription.But it is impractical and expensive to have an optometrist orophthalmologist available during the many hours that a retail opticalstore needs to be open in order to make a profit. This is even more soin the case of an optical department for a large retailer, such asWalmart or Target, where the retailer may be open 18 to 24 hours perday. Hosting a remote station that provides access to an optometrist orophthalmologist at any needed time, day or night, significantly enhancesthe profitability of the optical store or optical department.

In addition, the present invention is designed to comply with therecommendations related to telemedicine as set forth by the AmericanOptometric Association (AOA). It is believed that no other prior systemmeets all such recommendations for comprehensive eye examinations thatinclude subjective refractions with professional judgement by a doctorfor an accurate objective refraction.

DETAILED DESCRIPTION

I. Compliance with Recommendations of the American OptometricAssociation

A. Comprehensive Eye Examination Requirements

The present invention is designed to collect all of the information andperform all of these tests set forth by the AOA for a comprehensive eyehealth examination and vision analysis. Such requirements are set forthbelow.

1. Chief Complaint: assessment of the patient's reason for getting aneye exam.

2. General Physical Health History: complete health history to screenfor physical conditions and medications that may affect eyesight.

3. General Ocular Health History: complete eye health history includingfamily history of eye conditions, disease, or medication.

4. External and Internal Eye Health Evaluation: examination for thesigns of eye disorders, including cataracts and other eye disorders.

5. Current Prescription Analysis: evaluation of current lensprescription, if applicable.

6. Visual Acuity: test for the eyes' ability to see sharply and clearlyat all distances.

7. Refraction: test for the eyes' ability to focus light rays properlyon the retina at distances and close by.

8. Tonometry: test to measure internal fluid pressure of the eye(increased pressure may be an early sign of glaucoma).

9. Visual Coordination: check for external eye muscle balance andcoordination.

10. Accommodative Ability: test of the eyes' ability to change focusfrom distance to near.

Prior telemedicine schemes have not been designed to accomplish all ofthe above tasks. Indeed, many provide only refractive services.

B. Optimal Platforms for Telemedicine

In addition to the above, the present invention is designed to complywith the recommendations of the AOA with respect to optimal telemedicinerequirement—live interactive eye and vision telehealth services. Per theAOA, “live interactive eye and vision telehealth services” are thosethat use videoconferencing as a core technology. Participants areseparated by distance, but interact in real-time. In contrast“store-and-forward” eye and vision telehealth services refers to amethod of providing asynchronous consultations to referring providers orpatients. A history and a set of images are collected at the point ofservice and are transmitted for review by an eye doctor. In turn, theeye doctor provides a consultative report back to the referring provideror patient at the point of service. “Eye and vision remote patientmonitoring services” refers to personal health and medical datacollected from an individual in one location via electroniccommunication technologies, which is transmitted to a provider in adifferent location for use in care coordination and related support.

The present invention is also designed to comply with therecommendations of the AOA for optimal uses of technology in synchronoustelehealth uses. Per the AOA, for synchronous telehealth uses, acontrolled environment, including adequate lighting, and a highresolution video camera is typically required at the originating site,and a monitor with resolution matched to the camera resolution isrequired at the distant site. Videoconferencing systems work optimallywhen a high-speed connection speed is used. Slower connection speeds maynecessitate that the individual presenting the patient perform eitherstill image capture or freeze frame to render a quality image. Forasynchronous uses, a controlled environment, including adequatelighting, and a digital camera with a high pixel resolution is typicallyrequired. For systems that transmit over the Internet, secure encryptionand multi-factor authentication are recommended. Remote patientmonitoring solutions often take the form of software as a service, withclinical software that allows eye doctors and other clinical staff tomanage patient populations by exception. Direct-to-patient eye andvision health-related applications, including online vision tests andother mobile eye and vision-related applications, must also comply withthe above requirements.

The present invention is designed to comply with the recommendations ofthe AOA regarding credentialing and privileging. Per the AOA, the JointCommission (TJC) has implemented standards for telehealth/telemedicine.Under the TJC telemedicine standards, practitioners who render careusing live interactive systems are subject to credentialing andprivileging at the distant site when providing direct care to thepatient. The originating site may use the credentialing and privileginginformation from the distant site when certain requirements are met.Doctors who render services using store-and-forward systems are viewedby TJC as “consultants” and might not be required to be credentialed atthe originating site. However, standards can vary by state andorganization.

The present invention is also designed to comply with therecommendations of the AOA regarding privacy and confidentiality. Perthe AOA, practitioners who provide eye and vision telehealth servicesshould ensure compliance with the Health Insurance Portability andAccountability Act of 1996 (HIPAA), as amended, and its implementingregulations. The handling of records, faxes, and communications issubject to the same HIPAA standards as those that apply in a standardoffice environment. For asynchronous telehealth uses, HIPAA compliancelargely relies on the originating site informing patients that theirinformation will be traveling by electronic means to another site forconsultation. This should be noted in the consent form at the point ofservice, and the HIPAA notice of privacy practices. In addition, allelectronic transmissions should be encrypted and reasonable care shouldbe taken to authenticate those providers who have electronic access tothe records.

The present invention is also designed to comply with therecommendations of the AOA regarding licensing. Per the AOA, interactivetelehealth requires the equivalent of direct patient contact. In theU.S., telehealth using interactive technologies is generally restrictedto jurisdictions where the eye doctor is permitted, by law, to practice.In other words, the provider using interactive technologies is typicallyrequired to be licensed to practice in the jurisdiction in which thepatient is located. For store-and-forward applications, most statesrequire telehealth providers to be licensed in the same state in whichthe patient resides, even when he or she acts only as a consultant.Doctors of optometry and other appropriate, licensed providers who wishto provide store-and-forward consultations across state lines shouldlimit such consultations to originating states in which they arepermitted, by law, to provide care.

The present invention is also designed to comply with therecommendations of the AOA with respect to responsibility/liability. Perthe AOA, if direct services (doctor-to-patient) are provided (noassistance at the referring site), the consulting eye doctor bears fullresponsibility (and potential liability) for the patient's care. Thediagnostic and therapeutic recommendations rendered are based solely oninformation provided by the patient. Therefore, any liability should bebased on the information available at the time the consult was answered.In a consultative model (doctor-to-doctor), liability may be shared;however, the allocation of responsibilities will vary on a case-by-caseand state-by state basis. Doctors of optometry and other appropriate,licensed providers should verify that their liability insurance policycovers telehealth/telemedicine services, including those servicesprovided across state lines, if applicable, prior to the delivery of anysuch service.

C. Criteria for High-Quality Eye and Vision Telehealth Services

The AOA supports the use of eye and vision telehealth services providedby licensed eye doctors—doctors of optometry and ophthalmologists—andother appropriate, licensed professionals in certain instances, andsupports coverage of and payment for eye and vision telehealth services,when several important criteria are met. The present invention isdesigned to meet certain of the AOA's criteria as set forth below.

1. The standard of care must remain the same regardless of whether eyeand vision telehealth services are provided in-person, remotely viatelehealth, or through any combination thereof. Doctors may not waivethis obligation, or require patients to waive their right to receive thestandard of care. Further, a payor may not require either the doctor orpatient waive the right to receive the standard of care.

2. The use of eye and vision telehealth services may be appropriate forstandard basic data acquisition, gathering repetitive specific data,confirmation of expected therapeutic results, confirmation ofstability/or homeostasis, and notifications of changes in chronicconditions. Further uses may be appropriate as new evidence andtechnologies are made available.

3. The use of eye and vision telehealth services is not appropriate forestablishing the doctor-patient relationship, for an initial diagnosis,as a replacement for recommended face-to-face interactions, or as areplacement for partial or entire categories of care.

4. Eye doctors and other licensed professionals delivering eye andvision telehealth services must be licensed in the state in which thepatient receives services (subject to respective laws and regulations),and must abide by that state's licensure laws and regulations.

5. Patients must be made aware of potential limitations of the servicesthat can be provided via telehealth. Eye doctors or other licensedprofessionals delivering eye and vision telehealth services must, whenclinically appropriate, promptly refer patients for an in-persondiagnosis and/or care.

6. Patients or referring practitioners seeking eye and vision telehealthservices must have a choice of eye doctor, if possible, and must haveaccess, in advance, to the licensure and qualifications of the clinicianproviding services. The delivery of eye and vision telehealth servicesmust be consistent with state scope of practice laws in the state inwhich the patient is located at the time of the encounter.

7. The patient's relevant health history must be collected as part ofthe provision of eye and vision telehealth services. Appropriate healthrecords should be available to the consulting eye doctor prior to or atthe time of the telehealth encounter. Consulting eye doctors should havea good understanding of the culture, health care infrastructure, andpatient resources available at the site from which consults areoriginating. The provision of eye and vision telehealth services must beproperly documented. These health records should, when appropriate, beavailable at the consultant site and at the referral site.

8. The provision of eye and vision telehealth services should includecare coordination with the patient's primary care provider, and eyedoctor, if one exists. This coordination should include, at a minimum,identifying the patient's primary care provider and eye doctor in theeye and vision telehealth services referral record, and providing a copyof the health record to those members of the treatment team who do nothave electronic access to it. This provision is especially important sothat information regarding diagnoses, test results, and medicationchanges are available to the care team.

9. Organizations and clinicians participating in eye and visiontelehealth services should have an ongoing training program and currentlist of required criteria for both the distant and receiving sites. Inaddition, those programs that are using eye and vision telehealthservices should have documentation of their training programs for anytechnician who is capturing clinical images and for any clinician who isproviding consults. Each organization should also maintain documentationon how the program protects patient privacy, promotes high-qualityclinical and image data, continuity of care, and care coordination forpatients who may request or require subsequent in-person evaluations orprocedures.

10. While monitoring patients remotely, the regular interaction betweenclinical care coordination staff, patients, and their eye doctor(s) andother primary care providers is critically important for successfuloutcomes. Only FDA-approved devices being utilized in the manner forwhich they were approved may be used to monitor patients remotely. Therisks and benefits of medical devices should be properly and thoroughlyweighed through science and evidence to ensure efficacy and quality andto protect the public health.

11. Organizations and clinicians participating in eye and visiontelehealth services must have protocols for local referrals (in thepatient's geographic area) for urgent and emergency services. Mechanismsto facilitate continuity of care, follow-up care, and referrals forurgent and emergency services in the patient's geographic area must bein place. Any new prescriptions must be communicated directly to thepatient's care team (unless the team has easy electronic access to theeye and vision telehealth record).

12. When creating directories of participating eye doctors forestablishing network adequacy, an insurer may not consider access to eyeand vision telehealth services as a substitute for locally availabledoctors of optometry, who can offer a wide range of eye health andvision care services.

13. The AOA supports eye and vision telehealth services designed anddedicated to provide demonstrably high-quality patient care. The AOAdoes not support eye and vision telehealth services primarily focused onoffering access to prescriptions without conducting an adequate history,examination, patient diagnosis, and/or valid and proper doctor-patientrelationship.

14. With respect to the doctor-patient relationship:

(a) For eye and vision telehealth services where a referring providerultimately manages the patient (including prescriptions), the consultingeye doctor is not required to have a pre-existing, valid doctor-patientrelationship. It is optimal, however, if the patient has availableaccess to in-person follow-up with a local eye doctor when needed.

(b) For live interactive eye and vision telehealth services anddirect-to-patient eye and vision health-related applications, includingonline vision tests and other mobile eye and vision-relatedapplications, the consulting eye doctor must either: (i) Have anexisting doctor-patient relationship (having previously seen the patientin-person); or (ii) Before providing services, establish communicationwith the patient's existing care team, including the patient's eyedoctor, in order to document eye, vision, and systemic history, pastcomprehensive eye and other examinations, and any related patientdiagnosis; or (iii) Be a part of an integrated health delivery systemwhere the patient already receives care, in which the consulting eyedoctor has access to the patient's existing medical record and cancoordinate follow-up care.

15. The use of direct-to-patient eye and vision-related applications,including online vision tests and other mobile eye and vision-relatedapplications, raise several additional issues (and all of the abovecriteria still apply):

(a) Direct-to-patient eye and vision-related applications, based oncurrent technologies and uses, cannot replace or replicate in-personcomprehensive eye examination provided in-person by an eye doctor.

(b) The eye health portion of a comprehensive eye examination and therefractive portion of a comprehensive eye exam, based on currenttechnologies and uses, cannot be replaced or replicated bydirect-to-patient eye and vision-related applications.

(c) Screening for specific or groups of eye health issues usingtelehealth for direct-to-patient eye and vision-related applications,based on current technologies and uses, should not be used to diagnoseeye health conditions or as a replacement or replication for acomprehensive dilated eye exam. Screenings solely identify risk, whichis a risk that only an in-person comprehensive eye examination can beginto valuate, mitigate, and/or address.

(d) Refractive tests, including online vision tests and other mobilevision-related applications, cannot be, based on current technologiesand uses, used to provide a refractive diagnosis and/or an eyeglass orcontact lens prescription, due, in part, to these tests not currentlyincluding a controlled testing environment, subjective refraction, orprofessional judgement. Additionally, self-administered vision tests,based on current technologies and uses, cannot be relied on as accuratefor an objective refraction.

(e) Photographs obtained by patients, their family members, or theirfriends outside of a clinical setting may not be of adequate quality, ormay not include the information needed to make an accurate diagnosis.

II. Workflow for Remote Comprehensive Eye Examination

Turning to FIG. 1, shown is an overall system workflow diagram for anapparatus, method, and system for remote comprehensive eye examinations.Shown are workflows for the exam site 1100, central server (exam siteand remote technician connection) 1200, remote technician 1300, remotedoctor 1400, and central server (remote doctor connection) 1500.

The exam site workflow 1100 may initiate a connection to the centralserver (exam site and remote technician connection) 1200 on a specifiedport and wait for a response 1101. Similarly, the remote technician 1300may initiate a connection to the central server (exam site and remotetechnician connection) 1200 on a specified port and wait for a response1301. In both of these cases, the central server (exam site and remotetechnician connections) 1200 may also be listening for connections onspecified ports from exam sites and remote technicians 1201, which maybe different ports for exam sites and remote technicians. In the case ofthe exam site initiated connection, the central server (exam site andremote technician connection) 1200 may send a new port number back tothe initiating exam site 1100 to use for the connection 1202. The examsite 1100 may receive this new port number from the central server (examsite and remote technician connection) 1200 and disconnect from theoriginal port number 1102. Now, the exam site 1100 may initiate a newconnection to the central server (exam site and remote technicianconnection) 1200 using the new port provided by the central server (examsite and remote technician connection) 1200 and using an exam user IDand password 1103. The central server (exam site and remote technicianconnection) 1200 may detect the new connection from the exam site 1100over the updated port number and checks the IP address. If the IPaddress is the same as original exam site 1100 IP address, then theconnection may be kept open. If the IP address is different, then theconnection may be closed 1204. If the IP address is the same, and theconnection is kept open, then the central server (exam site and remotetechnician connection) 1200 may verify the exam user ID and password. Ifthe credentials don't match an existing account, then the connection maybe closed. If the credentials do match an existing account, thenconnection may be kept open 1206.

Similar to the case with the exam site, if the central server (exam siteand remote technician connection) 1200 receives a connection from theremote technician 1300, the central server (exam site and remotetechnician connection) 1200 may send a new port number to the initiatingremote technician 1300 to use for the connection 1203. The remotetechnician 1300 may receive this new port number from the central server(exam site and remote technician connection) 1200 and disconnect fromthe original port number 1302. Now, the remote technician 1300 mayinitiate a new connection to the central server (exam site and remotetechnician connection) 1200 using the new port provided by the centralserver (exam site and remote technician connection) 1200 and using anremote user ID and password 1303. The central server (exam site andremote technician connection) 1200 may detect the new connection fromthe remote technician 1300 over the updated port number and checks theIP address. If the IP address is the same as original remote technician1300 IP address, then the connection may be kept open. If the IP addressis different, then the connection may be closed 1205. If the IP addressis the same, and the connection is kept open, then the central server(exam site and remote technician connection) 1200 may verify the remoteuser ID and password. If the credentials don't match an existingaccount, then the connection may be closed. If the credentials do matchan existing account, then connection may be kept open 1207.

Once the remote user and site has been verified, the central server(exam site and remote technician connection) 1200 may send an updatedlist of remote technicians 1208 currently available to the exam site1100. The exam site 1100 technician may be informed if there are anytechnicians currently available 1104.

At the exam site 1100, the patient may fill out their history and otherinformation on a tablet PC or other medium, and that information 1105may be sent to the central server (exam site and remote technicianconnection) 1200. The central server (exam site and remote technicianconnection) 1200 receives this patient information, and the patient maybe added to the list of patients currently waiting for an eye exam. Thepatient list and history information for each patient may be sent to theremote technician 1300 and the approximate wait time 1209 may be sent tothe exam site 1100. At the exam site 1100, the selected patient and/ortechnician are informed of an approximate wait time 1106. At the remotetechnician 1300, the next patient waiting for an exam may be displayed,and patient history may be reviewed by the technician 1304. When theremote technician 1300 is ready, they may send a signal to the centralserver (exam site and remote technician connection) 1200 indicating thatthey may be ready to start the exam 1305. At the central server (examsite and remote technician connection) 1200, the patient may be movedoff the waiting list, and the exam site 1100 may be informed that theexamination may now begin for the selected patient 1210. At the examsite 1100, the patient and/or technician may be informed that the examis about to begin 1107. At the remote technician site 1300, the remotetechnician may select a predefined set of tasks for the exam or they maycreate a custom list of tasks that may be based on the patient'shistory. Verbal instructions may also be provided once the video link isestablished if available. Whenever possible, the required tasks may beautomated 1306 at the exam site 1100. At the central server (exam siteand remote technician connection) 1200, the video conference may link1211, 1212 the remote technician 1300 and exam site 1100. At the examsite 1100, the patient and/or technician is informed that the exam maybe ready to begin 1108. Video conference data may flow between the examsite 1100 and remote technician 1300 through the central server (examsite and remote technician connection) 1200. The task listed selected bythe remote technician 1300 may be sent 1307 through the central server(exam site and remote technician connection) 1200 to the exam site 1100.The central server (exam site and remote technician connection) 1200relays 1213 this information to the exam site 1100. At the exam site1100, the requested task may be presented to the local technician 1109.The requested tasks may be performed and results may be sent to theremote technician 1300 at each point where a reported flag has beeninserted or at the end of the task list if no report flags are present1111. During this phase, the system may interact 1110 with equipment atthe exam site 1100. The central server (exam site and remote technicianconnection) 1200 receives information and relays 1214 it to the remotetechnician 1300. The remote technician 1300 may receive they results ofthe tasks performed so far and may review the results 1308. If the taskis a remote refraction, the remote technician 1300 may remotely controlthe phoropter using the manufacturer's user interface 1309. At the examsite 1100, the remote phoropter may be controlled by the remotetechnician 1300 using the manufacturer's user interface 1112.Alternatively, the remote technician 1300 may modify the list ofremaining tasks and return a revised list back to the central server(exam site and remote technician connection) 1200 if desired 1310. Thisrevised task list may be sent to the exam site 1100 through 1307 thecentral server (exam site and remote technician connection) 1200. Duringthe remote phoropter exam, the remote technician 1300 may control thespecific eye charts or patterns that are displayed to the patient duringthe refraction 1311. The central server (exam site and remote technicianconnection) 1200 relays this control information 1215 to the exam site1100. At the exam site 1100, eye charts used during the exams may beremotely controlled by the remote technician 1300 or by the localtechnician 1113.

At the conclusion of the exam, the central server (exam site and remotetechnician connection) 1200 is passed all of the information collectedto this point and is informed that the remote technician 1300 portion ofthe eye exam is complete 1312. The final information from the remotetechnician 1300 is received by the central server (exam site and remotetechnician connection) 1200 and the exam site 1100 may be informed thatthe exam is complete. All exam results to this point 1216 may be storedon the central server (exam site and remote technician connection) 1200.At the exam site 1100, the exam is completed, and the video conferencelink may be disconnected and instructions may be displayed to wait forthe doctor to issue the final prescription 1115. The video conferencelink may be disconnected 1114 and the exam site 1100 is informed ifthere are any remote technicians 1300 currently available for anothersession 1104. At the remote location 1300, the video conference link mayend 1313. The remote technician 1300 may choose to examine more patientsat this point, or they may disconnect 1314. If they choose to examinemore patients, they may be informed of the next patient waiting for anexam by central server (exam site and remote technician connections)1200 and patient history can be reviewed by remote technician 1300 1304.

The remote doctor 1400 may initiate a connection to the central server(doctor connection) 1500 on a specified port and wait for a response1401. The central server (doctor connection) 1500 may also be listeningfor connections 1501 on specified ports from remote doctors 1400. Thecentral server (doctor connection) 1500 may send a new port number backto the initiating remote doctor 1400 to use for the connection 1502. Theremote doctor 1400 may receive this new port number from the centralserver (doctor connection) 1500 and disconnect from the original portnumber 1402. Now, the remote doctor 1400 may initiate a new connectionto the central server (doctor connection) 1500 using the new portprovided by the central server (doctor connection) 1500 and using a userID and password 1403. The central server (doctor connection) 1500 maydetect the new connection from the remote doctor 1400 over the updatedport number and checks the IP address. If the IP address is the same asoriginal remote doctor 1400 IP address, then the connection may be keptopen. If the IP address is different, then the connection may be closed1503. If the IP address is the same, and the connection is kept open,then the central server (doctor connection) 1500 may verify the user IDand password. If the credentials don't match an existing account, thenthe connection may be closed. If the credentials do match an existingaccount, then connection may be kept open 1504. The central server(doctor connection) 1500 may then add the remote doctor 1400 to the listof doctors currently online 1505. At the remote doctor 1400, once theconnection is established and verified by the central server (doctorconnection) 1500, the software may go into a wait state 1404 untilsomething is received from the central server (doctor connection) 1500.The remote doctor 1400 may indicate that they are ready to see the nextpatient 1405. The central server (doctor connection) 1500 may receive asignal that the remote doctor 1400 is ready to review their next patient1506. All patient history and exam information for the next patientwaiting for their final prescription is sent 1507 to the remote doctor1400 by the central server (doctor connection) 1500. The remote doctor1400 may receive the patient information from the central server (doctorconnection) 1500 for review 1406.

At the central server (exam site and remote technician connections)1200, the list of doctors currently logged into the system may bescanned using a set of rules. The appropriate doctor may be alerted andall patient information may be sent to the remote doctor 1400 for reviewif they are signed into the system. If they are not signed into thesystem, a text message or similar medium may be sent 1217. The remotedoctor 1400 may be alerted that patient information has been receivedand is waiting for review 1407. The remote doctor 1400 may review thepatient history and exam information and may determine the finalprescription. The prescription, along with any special instructionsand/or referral information is sent to the central server (exam site andremote technician connections) 1200, which is then passed on to the examsite 1100. The remote doctor's 1400 signature or other authorization mayalso be included 1408. The central server (exam site and remotetechnician connections) 1200 receives this information 1218, and relaysit to the exam site 1100. The exam site 1100 may be notified when theprescriptions and/or any special instructions are received from theremote doctor 1400 through the central server (exam site and remotetechnician connections) 1200 so that the local technician may benotified 1116. The final prescription and/or any special instructionsmay be printed locally along with the doctor's signature or otherauthorization and presented to the patient 1117. The patient mayacknowledge receiving the prescription and/or recommendations 1118. Theremote doctor 1400 may be informed through the central server (exam siteand remote technician connections) 1200 that the prescription and/orspecial instructions have been understood and accepted 1219. The remotedoctor 1400 may receive this confirmation of reception and understandingof prescription and information, and concludes the eye exam 1409. Theremote doctor 1400 may choose to disconnect at this time, or they maycontinue to see more patients 1410. If they decide to see more patientsthey may indicate that they are ready to see the next patient 1405. Atthe exam site 1100, if the exam site has electronic medical records(EMR), all patient and exam information may be uploaded to the EMR 1119.Product marketing material may be introduced to the patient at this timebased on a set of rules determined by the doctor 1120.

The system may also contain a combination hardware and automaticsoftware switch that allows the eye exam equipment to be used by thisremote comprehensive eye exam system, or by an on-site doctor to do astandard non-remote eye exam. The method of switching the equipment fromone mode to the other may be accomplished at the exam site through theuse of a single physical hardware switch.

The machine interface software automatically detects whether a local orremote exam is being done and directs the received output from the examdevices to the appropriate user-selectable location(s) at theappropriate time and in the preferred user selectable format. Theuser-selected data format can be in the form of file(s) that are droppedinto a shared network folder or the selected data format can be outputthrough a configurable serial port.

This hardware switching feature saves the exam site a significant amountof money because it allows the same eye exam equipment to be used forboth local and remote exams—a unique feature of this system. This avoidsthe need for the exam site to purchase one set of eye exam equipment fornon-remote eye exams and another set of equipment for remote exam use.

IV. System Operations

The following provides a comprehensive description of role of eachparticipant in the apparatus, method, and system for remotecomprehensive eye examinations: the patient, the local technician, theremote technician and the remote doctor. The patient may be assigned toa local eyecare technician, where the patient and the local eyecaretechnician are located at a local diagnostic center. The patient is thenassigned to a remote eyecare technician (possibly by the localtechnician), where the remote eyecare technician is located at a firstremote diagnostic center. The patient is finally assigned (possibly bythe local technician) to a eyecare doctor, where the eyecare doctor islocated at a second remote diagnostic center, which may or may not bethe same remote diagnostic center as the first remote diagnostic center.Thus, in some embodiments, the eyecare doctor, the remote technician andthe local technicians are in different locations.

A. The Patient

The patient portal and kiosk is a hand-held tablet computer with customsoftware that is used by the patient during the examination process.This tablet can be used to update the patient medical history, view thecurrent exam status, and also view previous prescriptions. The tabletwill also provide links to various websites and videos which can be usedto educate and entertain the patient while in the waiting area.

1. New Patient

When a new patient arrives at the doctor's office, the local technicianwill need to begin the process of gathering information about thatpatient to properly complete the examination. A vital step in thisprocess is providing a kiosk tablet to the patient for them to fill outforms requesting patient information.

The local technician needs to start the process on the kiosk tablet ofadding a new patient.

The local technician will need to click “Add Patient” to start theprocessing of adding a new patient into the system. When this button isclicked, the local technician Login Details dialog is displayed.

In this dialog, the technician will enter their username and password,which is also used to login to the patient portal. After thisinformation has been properly entered, the kiosk tablet will present apage requesting patient information. It is at this point that thetechnician would hand the tablet off to the patient, asking the patientto fill-in the online forms.

The following images display the form that the patient will fill-out onthe kiosk tablet. This form contains information such as name, address,birthdate, insurance information, signature, etc. Also, this form willallow the viewing of the Terms and Conditions and Privacy Policy, forthe patient's approval.

After the patient completes filling in the patient information andclicks the “Submit” button, the patient will be shown the login screen,where they can login to the patient dashboard. Details of the patientdashboard are contained in the following section.

2. Existing Patient

The patient will login to the patient portal, by filling in theirusername and password on the dialog as illustrated in the followingimage.

When the patient logs into the system for the first time, they will bepresented with the following dialog, where they will need to agree tothe Terms and Conditions and Privacy Policy to continue using thepatient portal.

At this point, the patient is now logged into the patient portal. Fromthe patient portal, the patient can view the current exam status, reviewprevious prescriptions, update personal information (address, phonenumber, etc.), and update their medical history, among other items.

When the patient logs into the patient portal, the patient dashboardwill be presented. The dashboard contains information about the currentexam status for the patient. The following shows the dashboard, with nopatients currently waiting for an examination.

There are 4 main sections to the patient dashboard. As the patient movesthrough each phase of the examination process, the appropriate sectionsof the dashboard will be updated. From this dashboard, the patient canview the status of various aspects of the examination.

Before the examination, the patient should update their medical history,by selecting the “Add Medical History” button along the left-hand sideof the screen. This will display the following form, which asks variousquestions about the patient's medical history.

3. Local Technician Status

When an examination is starting for the patient, the dashboard willchange to display data similar to the following screen capture. Thestatus is displayed as waiting for the local technician exam to begin.

Once the local technician has begun the exam process, the status on thepatient dashboard will be updated accordingly. In the following image,the patient's status has been updated to local technician exam inprogress, indicating that the patient is currently being examined by thelocal technician.

After the local technician's examination has completed, the patient willbe passed to the remote technician. While the remote technician isperforming the refraction, the patient's dashboard will be updated witha status indicating that the remote technician exam is in progress. Thedashboard will update to reflect the current status when the remotetechnician exam has completed, and the patient is waiting for the remotedoctor.

While the doctor is examining the patient, the dashboard is updated toreflect this status. When the exam has been completed, the patientdashboard will reflect the status.

4. Other Features

After one or more examinations have been completed on the patient, theycan use the “View Prescription” button to view the current and anyprevious prescriptions.

The update profile option will allow the patient to change personalinformation, including such items as address, employer, insurance, etc.The information requested on this form is the same as the informationrequested during the initial patient session at the doctor's office.

The patient may desire to change their login password for the patientportal. The “Change Password” button will allow the password to bechanged. To change the password, the patient must enter the oldpassword, and then enter the new desired password with confirmation.

To enhance the patient experience, the kiosk tablet will provideopportunities for education and entertainment. This is achieved bygiving the patient access to a select set of websites specificallychosen for patient enrichment. A button will be available on the menu inthe patient portal called “Information”, which when clicked will displaya list of links that the patient is allowed to access.

There are 3 levels to the selection process for websites. First, thesystem may provide a list of websites that all patients will have theability to access. Second, the group will be able to provide a list ofwebsites that the patient may access. Third, the exam site can add moresites to which the patient should be granted access.

Typically, these sites will be educational (YouTube videos, lenssuppliers, frame manufacturers, etc.). Access may also be granted toentertainment sites such as news, weather, and sports.

The kiosk hardware is a tablet computer that is configured to allow onlyone application to be run, and that is the custom kiosk software. Whenthe kiosk is booted-up, the kiosk software will run automatically withno intervention required from anyone at the doctor's office.

The kiosk software is an application centered around a custom webbrowser, designed to give the patient access to a limited number ofwebsites. The primary website that is available is the patient portal.This website provides information to the patient about current andprevious examinations.

The portal will optionally allow patients to have access to externalwebsites for educational and/or entertainment value, while waiting foran examination. The website available to the patient will be chosen bythe group, and the exam site. To restrict the websites that areavailable to the patient, the kiosk software will occasionally request awhitelist from the portal server. This whitelist will then be used toblock any website that is not on the whitelist.

The patient portal will also have a series of links, which will allowthe patient to browse the permitted websites. The links are notavailable while the patient is initially setting up their profile on thesystem, but once the patient has setup their profile, the links will bemade available.

To configure the allowed links and whitelist, the administrator, group,and site logins will have a configuration option available for settingthese items on the website.

B. The Local Technician

The local technician in the system is always physically located at theexam site. The local technician takes care of registering the patient,collecting patient history, and walking the patient through the entireexam process. The local technician also performs the initialpre-refraction tests prior to the actual refraction by a remotetechnician and the final review by a remote doctor. Such tests mayinclude non-contact tonometry glaucoma test, color blindness test,autorefractors and aberrometers.

If the patient is wanting contact lenses, the local technician may bedirected by the remote doctor to ask the patient try on specific triallenses, collect additional slit lamp images or videos with the triallenses in place, and then attach the resulting media files to thepatient's exam record so the remote doctor can verify the fit and makeadjustments as needed.

If the local technician is unable to recall their login password orusername, they can use the “Forgot Password?” or “Forgot Username?”recovery options as long as they still remember their email address. Therecovery options will email the recovery instructions to the localtechnician's email address. If they are unable to recall their emailaddress, they must contact the system administrator.

The local technician directly participates in a patient's eyeexamination and all results of the tests they perform at the exam siteare reviewed by the remote doctor. The role of the local technician isprimarily to observe the activity going on at their exam site and tomaintain local technician information and occasionally patientinformation for their exam site.

1. Eye Examination Operations

The various steps of an eye exam that are performed by the localtechnician after they login are described below. The remote technicianand remote doctor take over after the local technician has performed thepre-refraction tests. Their roles in the process are covered separatelyin the remote technician and remote doctor sections.

As shown in FIG. 2, the local technician performs the following steps.

Step 1: New Patient Registration 2001. This step is not required if thepatient has ever had a previous eye exam done at an exam site in thesame group as this exam site, otherwise the local technician mustregister the patient into the system. The demographic and patientmedical and visual history information can be entered directly by thepatient using a kiosk tablet, or the local technician can enter thisinformation for them if the patient prefers during a privateconsultation.

If the patient entered this information themselves using a kiosk tablet,they can now log into their patient portal using the ID and passwordthey just supplied. If the local technician entered all the patientinformation for them using the local technician's computer, the localtechnician can now log back into the web site normally.

Step 2: Check Availability 2002. This step is where the logged in localtechnician chooses the “Check Availability” menu option to select apatient and begin the eye exam process. Other patient search options arealso available from the drop down list.

A local technician may determine that the patient wants to see the firstavailable remote technician and remote doctor rather than waiting for aspecific remote technician or remote doctor. The number of logged inremote technicians and remote doctors who can see this patient will bedisplayed after the selections have been made.

Alternatively, the local technician may searched for specific remotetechnicians or remote doctors based on skills, acceptance of thepatient's insurance, and language. (Special note: Only doctors licensedin the state where the exam site is located will be allowed to see thepatient.)

After the local technician is finished selecting the patient, and theremote technician and remote doctor choice has been selected, the localtechnician dashboard will appear.

Step 3: Patient Waiting for Local technician—Add Patient Medical History2003. At this point, the local technician dashboard will automaticallyappear and the selected patient will now appear in the “Patient Waitingfor Local Technician” list. The patient medical history should now bereviewed and attached to the current eye exam. If the patient updatedtheir medical history through the patient portal prior to their eye examappointment, this process will be as simple as verifying the currenthistory information with the patient and clicking the “Submit” button.If the patient has not recently updated their history form through thepatient portal, the local technician must consult with the patient andupdate the history info for them at this time.

After the patient medical history form has been completed, the localtechnician will click the “Submit” button and the local techniciandashboard will once again appear.

Step 4: Patient Waiting for Local Technician—Start Session 2004. Whenthe local technician is ready to begin the local exam tests for aspecific patient, they will click that patient's “Start Session” button.

At this point, the machine interface software should be running in thebackground of the local technician's computer and they will click the“Send Patient ID” button. The machine interface will accept the patientID sent by the web site and will bring itself to the front of the webbrowser and be ready to accept data from interfaced local exam machines.The machine interface will use the patient ID to identify all local examtests performed during the current local exam test session.

Step 5: Local Exam Tests 2005. The local technician will now perform allrequired pre-refraction local exam tests for the current patient. Theinterfaced exam site machines will send the test results to the machineinterface. When all local exam tests have been completed, the localtechnician will click the “Save All Exam Tests” button and all examtests and associated media files will be sent to the web site andattached to the patient's current exam record.

An example of the machine interface screen is shown in FIG. 3.

Step 6: Submitting Exam Test Data 2006. The machine interface should nowbe minimized by clicking the— or X buttons on the top right corner ofthe main machine interface menu and the local technician's browserwindow should reappear. The exam tests the local technician just savedin the machine interface should show up in the “Completed Exam Tests”list within 60 seconds. Alternatively, the local technician can clickthe browser “Refresh” button to force the list to update itselfimmediately. The local technician can go back and repeat step 5 again ifthey need to perform additional tests for some reason. When the localtechnician has finished all local exam tests and is satisfied theresults of all tests were transferred properly to the web site, thelocal technician will click the “Submit” button at the bottom of thelocal technician observation page.

Pinhole Visual Acuity: The local technician will typically begin thepre-refraction test by performing a pinhole visual acuity test on eacheye. If the visual acuity results during this test indicate an issuewith the patient's vision that cannot be corrected with a subjectiverefraction, the local technician will typically terminate the eyeexamination with a referral to a local doctor.

Step 7: Patient Waiting on Remote Technician 2007. After successfullycompleting the prior step, the patient will be automatically moved tothe “Patient Waiting for Remote Technician” list. At this point duringthe patient's exam process, the local technician can do the following asit relates to a specific patient:

The video conference and subjective refraction “Session” with the remotetechnician can be started (if a remote technician has selected thepatient).

The exam tests done up to this point can be viewed or optionallyprinted.

The exam can be terminated (the local technician will be required toprovide a reason for the termination)

The patient can be reassigned to a different remote technician and/orremote doctor. When the “Start Session” button appears for a specificpatient, this means a remote technician has selected the patient and isready to begin a video conference and perform the subjective refraction.The local technician should position the patient properly behind thePhoropter and click the “Start Session” button when the button appears.This will begin the session with the remote technician.

Step 8: Video Conference and Remote Refraction 2008. The videoconference window will now appear in the local technician's browser. Thelocal technician will selected the specific webcam they want to use fromthe drop-down list and then they will click the button to start thevideo conference. If the remote technician has their video enabled, alive image will appear on the local technician's screen. If the remotetechnician has not enabled their video, the conference will be audioonly. Either way, the remote technician, local technician, and patientwill interact with one another as though they were located in the sameroom. The web site may popup a message asking for permission to use thelocal technician's camera and microphone. The local technician mustselect “Allow” or the video conferencing with the remote technician willnot work. At this point the local technician must click the “AllowPhoropter Connection” button which will allow the remote technician toconnect to the phoropter in the exam room and then the remote subjectiverefraction will begin. The refraction will include the same proceduresand tests that are typically used during a non-remote subjectiverefraction.

(Section III.C titled “Remote Technician” has further detail about theremote technician's role in this part of the process.)

When the remote technician has finished the refraction, the videoconference will end and the patient will be automatically moved to the“Patient Waiting for Remote Doctor” list.

Step 9: Patient Waiting on Remote Doctor 2009. After successfullycompleting the prior step, the patient will be automatically moved tothe “Patient Waiting on Remote Doctor” list. At this point during thepatient's exam process, the local technician can do the following as itrelates to a specific patient:

The video conference and optional subjective refraction “Session” withthe remote doctor can be started (If a remote doctor has selected thepatient).

The exam tests done up to this point can be viewed or optionallyprinted.

The exam can be terminated (the local technician will be required toprovide a reason for the termination)

The patient can be reassigned to a different remote doctor.

When the “Start Session” button appears for a specific patient, thismeans a remote doctor has selected the patient and is ready to begin avideo conference and begin the doctor evaluation. The local technicianshould position the patient properly behind the phoropter in case thedoctor wants to verify or refine the remote technician's subjectiverefraction. The local technician should then click the “Start Session”button when the button appears. This will begin the session with theremote doctor.

Step 10: Video Conference and Optional Remote Refraction 2010. The videoconference window will now appear in the local technician's browser. Thelocal technician will select the specific webcam they want to use fromthe drop-down list and then they will click the button to start thevideo conference. If the remote doctor has their video enabled, a liveimage will appear on the local technician's screen. If the remote doctorhas not enabled their video, the conference will be audio only. Eitherway, the remote doctor, local technician, and patient will interact withone another as though they were located in the same room.

The web site may popup a message asking for permission to use the localtechnician's camera and microphone. The local technician must select“Allow” or the video conferencing with the remote doctor will not work.

At this point the doctor's evaluation of all exam test data collected upto this point will begin. The doctor may optionally choose to verify orrefine the power of the subjective refraction done by the remotetechnician. The refraction will include the same procedures and teststhat are typically used during a non-remote subjective refraction. Theremote doctor will instruct the local technician to click the “Allowphoropter Connection” button (shown on the screen above) if the remotedoctor decides to connect to the exam room phoropter and verify orrefine the refraction.

(Section IV.D titled “Remote Doctor” has further detail about the remotedoctor's role in this part of the process.)

When the remote doctor has completed the evaluation, the videoconference will end and the patient will be automatically moved to the“Patient Waiting for Rx Print” list.

Step 11: Patient Waiting for Rx Print 2011. Patients who appear in thislist have already completed their eye examination and new eyeglass andoptional contact lens prescriptions have been authorized by the remotedoctor. If the patient wants a copy of their prescription emailed, thelocal technician should click the “Email Prescription” button first andthen click the “Print Prescription” button last. The prescription(s)will contain complete information you would typically find on anon-remote eye examination prescription along with the examiningdoctor's signature.

Step 12: Eye Exam Completed 2012. When the local technician hascompleted the previous step by printing a copy of the patient'sprescription(s), the patient is automatically removed from all waitinglists and their eye exam is finished.

If the local technician, remote technician, or remote doctor terminatesa patient's eye exam at any point before the prescription is issued, thepatient will be moved directly into the “Patient Terminated Exams” listwhich is the very last list shown on the local technician dashboard.

If the local technician views or prints the “prescription” for aterminated exam, it will contain the reason the exam was terminated andthe person's name who terminated the exam. This list is cleared eachday, so it will only include patients who were terminated during thecurrent day.

2. Maintenance Operations

The various maintenance operations that can be performed by the localtechnician after they login are described below.

Local technician dashboard. The local technician dashboard displays alist of patients currently waiting for the next stage of their eye exam.This allows the local technician to see at a glance the status of everypatient who is waiting. The local technician login does not have aninactive timeout, so they will not be logged out of the web site forinactivity.

This local technician dashboard allows the local technician to performthe following tasks:

The local technician can view a list of all patients at the exam sitewho are currently waiting to be seen by the local technician who islogged into the system. The patients in this list will appear in orderof how long they have been waiting for a local technician with those whohave been waiting the longest appearing at the top of the list.

The local technician can view a list of all patients at the exam sitewho are currently waiting to be seen by a remote technician to havetheir subjective refraction performed. The patients in this list willappear in order of how long they have been waiting for a remotetechnician with those waiting the longest appearing at the top of thelist. This list will also indicate if the patient is still waiting for aremote technician or if they are already in an active session with aremote technician.

The local technician can view a list of all patients at the exam sitewho are currently waiting to have the results of all the exam andrefraction tests reviewed by a remote doctor. The patients in this listwill appear in order of how long they have been waiting for a remotedoctor with those waiting the longest appearing at the top of the list.This list will also indicate if the patient is still waiting for aremote doctor or if they are already in an active session with a remotedoctor.

The local technician dashboard provides the local technician with a goodoverview of what is going on in their specific exam site location as itinvolves them. The local technician does not have an inactive timeout,so a local technician can stay logged in 24 hours a day without anyworry of being logged out.

Check Availability. The Check Availability menu option allows the localtechnician to start the exam process for a patient who is alreadyregistered in the system. Much more detail about the use of this menuoption is included in step 2 of the “Eye Examination” section of thisdocument.

Manage Patients. The local technician can use this menu option toperform the following tasks:

Add a new patient to this exam site

Edit the detail for an existing patient

Manage documents for an existing patient (scans of medical records,insurance cards, driver's license, etc.)

View the details for an existing patient

View and optionally print the current and past exam results andprescriptions for a patient

Email a copy of a prescription to a patient

The patient is required to agree to the terms and the patient'ssignature is also required.

View Report. This menu option allows the local technician to do thefollowing tasks:

Select the desired report type from the list of reports available tolocal technicians

Select the date range for the report

Submit the choices to create the report

View the resulting report

Print the resulting report

Export the resulting report

Search within the report

Reports available to the local technician will vary as additionalreports are added by the system administrator.

Update Profile. The update profile menu option allows the localtechnician to view and update their profile details.

Information. This menu option will display a list of subjects availablethrough internet links made available and assigned by systemadministrators. The subjects will typically be for training purposes,but the subject of the internet links made available through this menuoption will be appropriate for local technicians and will be controlledremotely by system administrators and can be changed remotely at anytime.

Change Password. This menu option simply allows the local technician tochange their login password. The “Change Password” option requires thelocal technician to enter their old password, enter the new password,and confirm the new password. Certain requirements must be met on thecomplexity of the new password or the change will not be allowed.

After the local technician has successfully changed their password, theymust log back in using the new password before they can continue usingthe system.

C. Remote Technician

The remote technicians in the system are responsible for performing thesubjective refraction part of the eye exam prior to the patient beingtransferred to the remote doctor. The phoropter equipment and eye chartused for the subjective eye exam is controlled remotely by the remotetechnician using special controller software running at the remotetechnician's location.

A video conference session is established between the remote technician,the patient, and the local technician during the subjective refraction.This allows the remote technician, local technician, and patient tointeract with each other during the subjective refraction in the sameway they would interact if the refraction was being performed locally.This interaction combined with the special digital refraction equipmentallows the remote technician to perform an extremely accurate subjectiverefraction and accurately check and record the patient's visual acuity.

The remote technician is allowed to review the lensometry,auto-refractor, and any subjective refraction test results that may havebeen previously performed during each exam session. The remotetechnician is not allowed to see the results of any other exam testsbecause the remaining tests must be evaluated by a remote doctor.

After the remote technician has completed all subjective refractiontests, the subjective refraction test results are reviewed by a remotedoctor. The remote doctor can verify and even adjust the subjectiverefraction test results if they so desire by using the video conferencesystem and controlling the phoropter exactly the same way as the remotetechnician.

If the remote technician is unable to recall their login password orusername, they can use the “Forgot Password?” or “Forgot Username?”recovery options. Both recovery options will email the recoveryinstructions to the remote technician's email address. If the remotetechnician is unable to recall the email address that was used whentheir account was created, they will not be able to use these recoveryoptions. In that case, they must contact the system administrator.

The remote technician directly participates in the patient's eyeexamination, but they also have a few maintenance operations they canperform as needed.

1. Eye Examination Operations

As shown in FIG. 4, the various subjective refraction related eyeexamination operations that are performed by the remote technician afterthey login are described below.

Step 1: Remote Technician Dashboard 4001. The remote techniciandashboard provides the remote technician the ability to get a goodoverview of everything in the system that will involve the specificremote technician who is logged in. The remote technician login has a 30minute timeout, so they will be logged out of the system automaticallyif they have not performed any operations within the last 30 minutes.

This remote technician dashboard allows the remote technician to performthe following tasks:

The remote technician can view a list of all patients currently waitingto have their subjective refraction performed. This list will containpatients waiting for any remote technician and patients waiting for thisspecific technician. Patients who are waiting for a different remotetechnician will not appear in this list. The patients in this list willappear in order of how long they have been waiting with those waitingthe longest appearing at the top of the list.

The remote technician can view a waiting patient's previous lensometry,auto-refractor, or refraction test results.

The remote technician can terminate an eye examination for any reason.If the remote technician terminates an eye examination, they arerequired to enter the reason they terminated the exam.

The remote technician can start the subjective refraction session. Whenthe session begins, the remote technician will begin a video conferencewith the patient and begin the subjective refraction by remotelycontrolling the phoropter.

Step 2: Begin Video and/or Audio Conference with Patient 4002. When theremote technician clicks the “Session” button, the remote technicianshould then select the webcam they want to use for the video conferencewith the local technician and patient from the drop down list. After thecorrect webcam is selected, they should then click the icon to send asignal to the local technician that the remote technician is ready tobegin the refraction. The video conferencing system allows the remotetechnician to communicate and interact with the patient and localtechnician as though they were in the same room.

The web site may popup a message asking for permission to use the remotetechnician's camera and microphone. The remote technician must select“Allow” or the video conferencing with the patient and local technicianwill not work.

Step 3: Subjective Refraction Exam Session 4003. After the videoconference session has been established, the remote technician will thenclick a button on the web page to connect to the phoropter in the examlane where the patient is located. At the same time, the localtechnician will use a button on their web page to allow the connection.Security implemented in this system makes it impossible for a remotetechnician to connect to the wrong phoropter. Once thecontroller/phoropter/eyechart connection has been established, theremote technician will have control of the phoropter and the eyechartand can begin the refraction. The digital equipment being used in thissystem allows the remote technician to perform a complete subjectiverefraction and related tests that will be at least as accurate asperforming these tests locally. The remote technician will observe allprecautions and “best practice” techniques as would be used for atypical non-remote subjective refraction.

Normal Visual Acuity: The remote technician will check the patient'svisual acuity for each eye and then for both eyes together under thefollowing conditions:

With no correction for the right and left eye

With no correction for both eyes together

With their previous prescription for the right and left eye

With their previous prescription for both eyes together

Subjective Distance Vision Refraction: The remote technician willremotely control the phoropter and eye chart to perform a distancevision subjective refraction on each eye. The subjective refractiontests performed for distance vision will be the same as the testsnormally performed during a non-remote subjective eye examination. Thesteps will typically include the following and in the following order:

Refine the right eye sphere power

Refine the right eye cylinder axis

Refine the right eye cylinder power

Refine the right sphere power one last time

Refine the left eye sphere power

Refine the left eye cylinder axis

Refine the left eye cylinder power

Refine the left sphere power one last time

Refine the right eye sphere using the Red/Green duochrome test

Refine the left eye sphere using the Red/Green duochrome test

Perform the binocular balance tests with both eyes together

Subjective Near Vision Refraction: The remote technician will remotelycontrol the phoropter and eye chart to perform a typical near visionrefraction if the patient is beyond a certain age or if the patientindicates they are having difficulty seeing at close distances orreading. The subjective refraction tests performed for near vision willbe the same as the tests typically performed during a non-remotesubjective eye examination.

Final Visual Acuity: The remote technician will now use the eye chart toperform the final visual acuity check for distance and near with the newprescription and save all test results.

New distance vision visual acuity for the right eye

New distance vision visual acuity for the left eye

New distance vision visual acuity with both eyes together

New near vision visual acuity for the right eye

New near vision visual acuity for the left eye

New near vision visual acuity with both eyes together

The phoropter and eye chart controller is not necessarily the propertyof the system so the appearance and functionality of the controller willvary from one equipment manufacturer to another. An example of thecontroller menu that is used by the remote technician to remotelycontrol a Reichert VRx phoropter and eye chart during the subjectiverefraction is shown in FIG. 5.

Step 4: Transfer the Subjective Refraction and Visual Acuity TestResults to the Web Site 4004: When the remote technician has completedall subjective refraction tests, the results of all tests are sent fromthe phoropter to the machine interface at the exam site, and then on tothe web site. The remote technician will then click the “Get RefractionData” button and the newest refraction done during the current examsession will be loaded into the form. The remote technician can thenchoose the type of lens the patient requests or that is indicated by thepatient's required lens power. The remote technician may also choose toadd comments for the remote doctor who will be doing the finalevaluation.

Step 5: Final Review and Transfer to the Remote Doctor 4005: When theremote technician is satisfied all important information has been added,they will click the submit button. The web site will verify everythingis valid and will then take the remote technician back to the remotetechnician dashboard and remove the patient from the patient waitinglist. At this point, the patient will be moved into the remote doctor'swaiting list.

2. Maintenance Operations

The various maintenance operations that can be performed by the remotetechnician after they login are described below.

Remote Technician Dashboard. The remote technician dashboard providesthe remote technician the ability to see a list of patients who arewaiting for refractions. Details about the remote technician dashboardare included in the previous “Eye Exam Operations” section of thisdocument.

View Report. This menu option allows the remote technician to do thefollowing tasks:

Select the desired report type from the list of reports available toremote technicians

Select the date range for the report

Submit the choices to create the report

View the resulting report

Print the resulting report

Export the resulting report

Search within the report

Reports available to the remote technicians will vary as additionalreports are added by the system administrator.

Update Profile. The update profile menu option allows the remotetechnician to view and update their profile details

Information. This menu option will display a list of subjects availablethrough internet links made available and assigned by systemadministrators. The subjects will typically be for training purposes andappropriate for remote technicians. The subject of the internet linksmade available through this menu option is controlled remotely by systemadministrators and can be changed remotely at any time.

Change Password. This menu option allows the remote technician to changetheir login password. The “Change Password” option requires the remotetechnician to enter their old password, enter the new password, andconfirm the new password. Certain requirements must be met on thecomplexity of the new password or the change will not be allowed. Afterthe remote technician has successfully changed their password, they mustlog back in using the new password before they can continue using thesystem.

D. Remote Doctor

The remote doctors in the system are responsible for evaluating theresults of all tests performed during the eye examination process andthey may optionally verify or refine the subjective refraction performedby the remote technician. The phoropter equipment and eye chart used forthe subjective eye exam can be controlled remotely by the remote doctorusing special controller software running at the remote doctor'slocation.

A video conference session is established between the remote doctor, thepatient, and the local technician during the doctor's evaluationsession. This allows the remote doctor, patient, and local technician tointeract with each other in the same way they would interact if thedoctor's evaluation was being performed locally. This interactioncombined with the use of the most modern examination equipment allowsthe remote doctor to perform an extremely thorough evaluation that is atleast as accurate as a non-remote doctor evaluation.

The remote doctor is required to review the results of all exam teststhat have been previously performed during each exam session includingany media files that may be attached to any exam test. The doctor isalso allowed to review all patient history information and anyinformation collected during any previous eye exam that is on file. Theremote doctor is also allowed to verify or refine any subjectiverefraction previously performed during this exam session.

After the remote doctor has reviewed everything, they may issue aprescription for eyeglasses, optionally issue a prescription for contactlenses, or they may choose to terminate the eye exam. The doctor willnot issue a contact lens prescription unless the patient has requestedcontact lenses and all contact lens related tests and fitting operationshave been successfully performed.

If the remote doctor is unable to recall their login password orusername, they can use the “Forgot Password?” or “Forgot Username?”recovery options. Both recovery options will email the recoveryinstructions to the remote doctor's email address. If the remote doctoris unable to recall the email address that was used when their accountwas created, they will not be able to use these recovery options. Inthat case, they must contact the system administrator.

The remote doctor directly participates in the final steps of thepatient's eye examination and makes the final decisions, but they alsohave a few maintenance operations they can perform as needed.

1. Eye Examination Operations

As shown in FIG. 6, the various evaluation and subjective refractionrelated operations that can be performed by the remote doctor after theylogin are described below.

Step 1: Remote Doctor Dashboard 6001. The remote doctor dashboardprovides a good overview of everything in the system that will involvethe specific remote doctor who is logged in. The remote doctor login hasa 30 minute timeout, so they will be logged out of the systemautomatically if they have not performed any operations within the last30 minutes.

This remote doctor dashboard allows the remote doctor to perform thefollowing tasks:

The remote doctor can view a list of all patients currently waiting tohave their eye exam tests evaluated and their eyeglass and optionallycontact lens prescriptions issued. This list will contain patientswaiting for any remote doctor and patients waiting for the specificdoctor who is logged in. Patients who are waiting for a different remotedoctor will not appear in this list. The patients in this list willappear in order of how long they have been waiting with those waitingthe longest appearing at the top of the list.

The remote doctor can see the group and exam site name and address whereeach patient is physically located.

The remote doctor can view the results of all tests performed for anywaiting patient.

The remote doctor can terminate an eye examination for any reason. Ifthe remote doctor terminates an eye examination, they are required toenter the reason they terminated the exam.

The remote doctor can start the eye exam evaluation session. When thesession begins, the remote doctor will typically begin a videoconference with the patient, begin evaluating the test results, andoptionally control the phoropter remotely if they want to verify orrefine the subjective refraction results.

Step 2: Begin Video and/or Audio Conference with Patient 6002. When theremote doctor clicks the “Add Prescription” button as shown on thedoctor's dashboard above, the webcam and prescription web pages willdisplay. The remote doctor should then select the webcam they want touse for the video conference with the local technician and patient fromthe drop down list. After the correct webcam is selected, they shouldthen click the icon to send a signal to the local technician that theremote doctor is ready to see the patient and begin the evaluationsession.

The web site may popup a message asking for permission to use the remotedoctor's camera and microphone. The remote doctor must select “Allow” orthe video conferencing with the patient and local technician will notwork. The video conferencing system allows the remote doctor tocommunicate and interact with the patient and local technician as thoughthey were in the same room.

Step 3: Optional Subjective Refraction Verification or Refinement 6003.After the video conference session has been established, the remotedoctor can optionally verify or refine the refraction done by the remotetechnician. A button on the web page allows them to connect to thephoropter in the exam lane where the patient is located. At the sametime, the remote doctor will use a button on their web page to allow thephoropter connection. Security implemented in this system makes itimpossible for a remote doctor to connect to the wrong phoropter. Oncethe controller/phoropter/eyechart connection has been established, theremote doctor will have control of the phoropter and the eyechart andcan begin the refraction verification or refinement. The digitalequipment being used in this system allows the remote doctor to performa subjective refraction and related tests that will be at least asaccurate as performing these tests locally. The remote doctor willobserve all precautions and “best practice” techniques as would be usedfor typical a non-remote subjective refraction if they do choose toverify or refine the refraction during their evaluation.

The phoropter and eye chart controller is not the property of the systemso the appearance and functionality of the controller will vary from oneequipment manufacturer to another. An example of the controller menuthat may be used by the remote doctor to remotely control a Reichert VRxphoropter and eye chart is shown in FIG. 5. Another model of a phoroptermay also be used.

Step 4: Doctor Evaluation 6004. The video conference will continue whilethe remote doctor is reviewing all exam test results for the currentpatient. The doctor may choose to carry on a conversation with thepatient while the test results are being examined. The web site will NOTallow the doctor to issue a prescription until they have reviewed theresults of every exam test, all attached media files, and the patient'svisual and medical history information. This system behavior assuresthat the remote doctor will review everything available, which makes thesystem significantly more thorough than a typical non-remote eyeexamination.

During the comprehensive eye exam, images of the patient's eyes aretypically collected by various eye exam devices such as a fundus camera.The remote eye exam system contains a feature that allows the remote eyedoctor to remotely display any or all images of the eye to the patientthat were produced during the eye exam. This is typically done duringthe remote doctor's video/audio conference with the patient. This allowsthe doctor to verbally explain things of interest or concern that may befound in any or all of the eye exam images while the patient is lookingat the actual image. This feature also allows the remote doctor toremotely highlight areas of interest on any of the eye exam images usingcircles, lines, squares, text or freehand drawing and all of theseannotations appear on the image being displayed to the patient. Thisfeature allows the remote doctor to be as detailed as needed whenreviewing images produced during the patient's eye exam.

During the comprehensive eye exam, video recordings of the patient'seyes are typically collected by various eye exam devices such as a videoslit lamp. The remote eye exam system contains a feature that allows theremote doctor to remotely display any or all videos of the eye to thepatient that were produced during the eye exam. This is typically doneduring the remote doctor's video/audio conference with the patient. Thisallows the remote doctor to verbally explain things of interest orconcern that may be found in any or all of the eye exam videos while thepatient is watching the actual video. This feature allows the remotedoctor to stop or pause the video at various points of interest toexplain an image in the video in greater detail. This feature alsoallows the remote doctor to remotely highlight areas of interest on thevideo image using circles, lines, squares, text or freehand drawing andall of these annotations appear on the video being displayed to thepatient. This feature allows the remote doctor to be as detailed asneeded when reviewing videos produced during the patient's eye exam.

When the remote doctor has reviewed an exam test for the current examsession along with all media files attached to the exam test, the tabfor that exam test will turn green. Exam test results that have not beenfully reviewed will remain light blue.

In addition to the exam tests, the remote doctor is also required toreview the patient's visual and medical history information before theyare allowed to issue a prescription.

The remote doctor may choose to review information from prior eye exams,but they are not required to do so.

The remote doctor will click the “Copy Refraction to This Form” buttonwhen they are satisfied the most recent refraction done during today'seye exam is accurate and correct. This will automatically load the mostrecent refraction data into the remote doctor's prescription form.

If the patient requested contact lenses and adequate testing has beendone to proceed with a contact lens exam, the doctor will place a checkmark in the “Add Contact Lens Prescription” checkbox. The remote doctormay instruct the local technician through the video conferencing systemto have the patient insert specific trial contact lenses and provideadditional slit lamp images and/or video so the remote doctor canevaluate the fit. The doctor will repeat this process until the contactlens is correct.

Start Video Conferencing system: The remote doctor will typically beginthe evaluation with the patient by starting a video conference session.This will allow the doctor to interact with the patient in the same waythey would do in a non-remote eye exam.

Review Exam Test Results: The remote doctor will review all exam testsresults and this will typically involve the following:

Mandatory: Review all exam tests performed by the local and remotetechnicians. This will include all tests that are normally performedduring a typical non-remote eye examination.

Mandatory: Review all media files that may be attached to any exam test.

Mandatory: Review the patient's medical history.

Optional: Verify or refine the subjective refraction by the remotedoctor's use of the phoropter remotely and applying professionaljudgement.

Optional: View the exam test results of any previous eye exam performedthrough this system.

Optional: View the patient history attached to any previous eye examperformed through this system.

Mandatory: Issue an eyeglass prescription or the doctor may choose toterminate the eye exam and provide a referral if necessary in theirprofessional opinion. If the doctor terminates the exam, they MUSTprovide a reason and optionally provide a referral.

Optional: They may issue a contact lens prescription if the patient asksfor contacts and all tests and fitting requirements for contact lenseshave been successfully performed.

In addition, there may be times when the remote doctor observessomething during the exam that requires a referral to a specialist. Thiswould typically happen while the remote doctor is evaluating the resultsof the eye exam tests during the video conference with the patient. Theremote comprehensive eye exam system contains an automatic doctorreferral system allows the remote eye doctor to simply click a referralbutton during the patient's eye exam if a referral is required.

The referring doctor is able to choose from a list of referral doctorsalong with their location and the areas in which they specialize. Thereferring doctor will typically choose a referral doctor located nearthe exam site where the patient is located. They will also typicallychoose a referral doctor who specializes in the appropriate area ofexpertise that is of concern on that particular patient.

After the remote doctor has completed the eye exam, the system willautomatically print a referral letter at the exam site to be given tothe patient and/or sent to the referral doctor. It will optionally printthe results from all exam tests along with all the remote doctor's notesthat can be given to the patient, or sent directly to the referraldoctor.

This feature saves the remote doctor considerable time compared tomanually finding a referral doctor, preparing the referral letter, andpreparing the exam data for the referral doctor. The ease of use of theautomatic referral system also encourages the remote doctor to refer apatient anytime he/she sees anything of concern.

Step 5: Final Review and Submit Prescription(s) 6005. The remote doctorcan now optionally attach comments to the final prescriptions beforesubmitting them to the system. When the remote doctor is satisfied allimportant information has been added to the prescription(s), they willclick the submit button. The web site will verify everything is validand will then take the remote doctor back to the remote doctor dashboardand remove the patient from the patient waiting list.

The remote doctor is now ready to see the next patient that appears intheir waiting list.

2. Maintenance Operations

The various maintenance operations that can be performed by the remotedoctor after they login are described below.

Remote Doctor Dashboard. The remote doctor dashboard provides the remotedoctor the ability to see a list of patients who are waiting for adoctor to see them and evaluate the test results and issue theirprescription(s) Details about the remote doctor dashboard are includedin the previous “Eye Examination Operations” section of this document.

View Report. This menu option allows the remote doctor to do thefollowing tasks:

Select the desired report type from the list of reports available toremote doctors

Select the date range for the report

Submit the choices to create the report

View the resulting report

Print the resulting report

Export the resulting report

Search within the report

Reports available to the remote doctors will vary as additional reportsare added by the system administrator.

Update Profile. The update profile menu option allows the remote doctorto view and update their profile details.

Information. This menu option will display a list of subjects availablethrough internet links made available and assigned by systemadministrators. The subjects will typically be for training purposes andappropriate for remote doctors. The subject of the internet links madeavailable through this menu option is controlled remotely by systemadministrators and can be changed remotely at any time.

Change Password. This menu option allows the remote doctor to changetheir login password.
